Abstract: A device, including a non-radioactive detection source, configured to detect airborne particulates and/or gases in an environment by applying a voltage bias to the non-radioactive detection source to create at least one detecting condition, and determining if airborne particulates are present within the at least one detection condition. A method of creating a detecting condition for airborne particulates and/or gases in an environment, the method including the steps of coupling a pair of electrical conductors to a nanocellular material, and applying a voltage bias to the pair of electrical conductors.

Abstract: A system for measuring a status of a detection device having a component transformable between a plurality of configurations includes a fiber optic cable for transmitting light. The at least one fiber optic cable defines a node arranged in communication with the component. A control system is operably coupled to the fiber optic cable such that scattered light reflected from the component and returned to the node is transmitted to the control system. The control system analyzes the scattered light to determine the configuration of the component.

Abstract: A detector assembly for a duct of a heating ventilation and air conditioning system includes an outer housing having at least one through hole formed therein, an inner sampling support receivable within a hollow interior of the outer housing, and at least one detector mounted to the inner sampling support. The at least one detector is axially aligned with the at least one through hole when the inner sampling support is installed within the hollow interior of the outer housing. The at least one detector is operable to sample air within the duct to detect a hazardous condition.

Abstract: An illustrative example monitoring device includes a plurality of radiation sources that respectively emit a different type of radiation. At least one radiation detector is situated to detect radiation emitted the radiation sources and reflected off airborne particles. The radiation detector has a first sensitivity configured for detecting a concentration of the particles within a first range and a second sensitivity configured for detecting a concentration of the particles within a second, different range. A processor is configured to determine a ratio of the types of detected radiation, a type of the particles reflecting the detected radiation based on the ratio, and the concentration of the particles reflecting the detected radiation based on the first or second sensitivity.

Abstract: A combined capability sensor includes a first laser source and a second laser source. The first laser source is configured to emit light having a wavelength in at least one of an infrared spectrum and a visible spectrum and the second laser source is configured to emit light having a wavelength in a blue or ultraviolet spectrum. A director is configured to direct the first and second laser source to a detection zone. A first sensor is configured to detect scattered light originating from the first laser source, thereby detecting a presence of smoke in the detection zone. A second sensor is configured to detect fluoresced light originating from the second laser source, thereby detecting a presence of a biological agent in the detection zone.
